Forever Frozen? Future Challenges for Ground
On a typical day, in a typical town, in a city almost anywhere in North America, roads and highways are filled with people going about their everyday business — commuting to work, delivering goods and...

The State of Soil Improvement in China: The G-I Soil Improvement Committee’s China Scan Tour
During the last four decades, China has made significant improvement in various sectors of its infrastructure, including high-speed railways, long-span and cross-sea bridges, large dams, long- and large-diameter...

We Struck Water! Discovery of Artesian Groundwater Solves A 50-Year-Old Landslide Puzzle
Some unstable slopes fail dramatically, but most can be characterized by gradual, if not monotonously slow, movements. Yet these latter situations can pose a dilemma when a temporary repair is much simpler...
